Hi Siman,
Thanks for the valuable and detailed feedback, very much appreciated.
I've never seen
changedetection.com before but it looks like a very interesting service. I can see why people are hooked on it, it seems like a useful tool to hook into something like IFTTT.
Pricing is definitely something we have under test at the moment (you get 1000 free checks and 20 free SMS alerts on sign up). We're experimenting with an Amazon style pay-for-use model, billed monthly, currently we charge $0.002 per check, 1 check per hour equates to around 720 checks per month which would cost $1.44. The pricing is on our landing page, but I'm going to take that as feedback that its just not visible enough - we'll fix that up. I 'borrowed' Pingdom's pricing structure for the SMS alerts, I suspect their business model is built around consumption of SMS's rather than the checks themselves. I'd be keen for feedback on what a reasonable price for both would be. This is actually one of the hardest things I'm finding, setting a reasonable price point (one which everyone wins) so any thoughts you have would be most appreciated.
I take your point about the maximum check frequency, i'll do some experimentation with the UI to see how we can do this nicely. I also need to work out exactly what the maximum check frequency would be in order to be profitable. This leads a little back in to the price point question, would it be more appealing to purchase a 'pack' of checks, similar to the SMS packs and auto top up when the packs expire?
I like the "Change alert" concept, it seems that theres a "low frequency" group of users that would find this appealing. Thanks again for all the feedback.
